Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644994, here are decompositions:

3 + 8644991 = 8644994
31 + 8644963 = 8644994
37 + 8644957 = 8644994
67 + 8644927 = 8644994
151 + 8644843 = 8644994
223 + 8644771 = 8644994
271 + 8644723 = 8644994
487 + 8644507 = 8644994

Showing the first eight; more decompositions exist.
